Value Collection 720-2160 Ball End Mill 5/16 in 2 Flute Hss

Product Description

The VALUE COLLECTION 720-2160 is a double-end ball end mill designed for milling contoured surfaces, slots, and three-dimensional profiles in metal, plastic, and composite materials. Manufactured from M2 high speed steel with a bright/uncoated finish, this tool delivers reliable performance in general-purpose machining applications. The ball nose geometry produces a full radial cutting edge, making it well suited for finishing passes and profiling work. With a 5/16 inch cutting diameter, 2-flute configuration, and a 30-degree right-hand helix, it balances chip evacuation with surface finish quality. The double-end design provides two usable cutting ends, extending tool life between replacements.

This end mill is used in manual milling machines and CNC machining centers for light-to-medium-duty operations in job shops, maintenance facilities, and production environments. Typical applications include die and mold work, contour milling, and pocket finishing where a spherical cutting tip is required. The 3/8 inch shank diameter fits standard ER and end mill holders common in vertical mills and machining centers. The standard overall length of 3-1/8 inches suits most general-purpose setups without requiring extended reach tooling.

Key Features

• Double-end design provides two cutting ends for extended tool utility
• M2 high speed steel construction offers toughness and wear resistance in general-purpose machining
• 30-degree right-hand spiral helix promotes efficient chip evacuation and smooth cutting action
• Bright/uncoated finish suitable for use with a wide range of cutting fluids and dry cutting conditions
• 2-flute configuration balances cutting speed with chip clearance in slotting and profiling passes
• Ball nose geometry enables contouring, radius profiling, and three-dimensional surface work

Compatibility

Designed as a general-purpose replacement or standard-stock ball end mill compatible with any milling machine or machining center equipped with a holder accepting a 3/8 inch shank diameter.

Installation Notes

Installation is performed by a machinist or tooling technician. The machine spindle must be fully stopped and de-energized before changing tooling. Secure the shank in a properly sized end mill holder or collet and torque to the machine manufacturer's specification using appropriate toolholder wrenches. Inspect the cutting edges for chips or damage before use, and confirm runout is within acceptable tolerance for the intended operation.
